Application filed November 25, 1925, Serial No. 71,387, and. in FranceDecember 4, 1924.

The present invention has for its object a wrench for tightening andreleasing nuts, characterized in that on each side of the'end of a leverare secured two disks of metal of appropriate thickness, each of saiddlsks presenting an opening of different size permitting oi: grippingbolts of correspondlng diameter. The number of bolts to which the wrenchcan be applied is equal to the number of openings presented respectivelyby each of the disks. These latter may be fixed or turnable on an axisin order to present successively at the most suitable angle, theirdifiierent openings.

The accompanying drawing shows, by way of example, an embodiment of thepresent invention and its different manners of applications:

Fig. 1 is an elevation of a wrench, Fig. 2 is a side view of same, Figs.3, 4, 5 are elevations of three out wrenches. 7

Figs. 6 and 7 are views respectively in section and in plan of anassembly of disks and of a lever which form by their combination amodified construction.

At one extremity of the lever 0: (Figs. 1 and 2) are secured by means ofa pivot 7), two disks 0, d which are interchangeable and rotatable andare held stationary at any desired adjustment by a bolt and wing nut e,which pass through them and through the lever a, said bolts and saidlever having openings for this purpose. I

The disks present around their periphery, recesses f, g, h, z', y, is,Z, m, corresponding 7 each to a different diameter of bolt and which canbe brought, by rotation, to the working position. It is thus possible,in the position indicated in Fig. 1, to grip the nuts with the recessesf, g, j, 70, the stems of the bolts resting in the corresponding recessof the disk which is not used. To utilize the recesses h, 2', Z, m, thenut e is released and the disks are turned through 180 degrees or 90degrees and are then secured in their new position by the said nut.

The second extremity of the lever a can be of any appropriate shapedesired; it may serve as a wrench, as a tire remover as in diiierdicatedrespectively at n (Fig. 1) and at 0 (Fig. 3), as a screw driver, or anyother instrument.

The modified construction shown at Fig.

3 comprises the disks 0 d having three recesses, each disk having toturn through 120 degrees to present a recess of a different diameter.

Instead of being movable, the disks 0 d can be secured to the lever a bytwo rivets p as shown in Figs. 4 and 5. As previously, the secondextremity of the lever can serve for any purpose and particularly it cansimilarly be furnished with two disks 0, d which increasesproportionately the number of nuts which can be treated by a singlewrench, as shown at Fig. 5.

The disks can carry recesses and openings I of any shape to grip anytype of nuts, hexagonal, square, etc., of any diameters. They can befixed to the lever either byrivets or bolts.

In order to render easier the changing of the disks, the lever a is, asshown in Fig. 7, provided at its extremity with a recess q, in whichfits the spindle 1' which unites two disks 8, t, which are integral withone an other. A screw 10, whose head rests'on the disk 8, passes throughthe hole '0 of the lever a and screws into the plate t which isscrewthreaded for this purpose.

Therefore, by the simple unscrewing or screwing up of the screw 10, thedisks can be removed or put in position to correspond with the diametersof the bolts to be tightened or loosened.

I claim:

1. A wrench for nuts comprising a lever,

a pair of discs having peripheral recesses to engage nuts, said discsbeing pivotally mounted on said lever, said lever having an opening andsaid discs being each provided with a series of openings, any one ofwhich may be brought by partial rotation of the discs into alignmentwith said opening of 515 the lever and a bolt insertable through saidopenings of the discs and lever to secure the discs in any desiredadjusted position.

2. A wrench comprising a lever havingan opening spaced from one end andan open I slot in said end, a pair of discs having peripheral nutengaging recesses, and also having a series of openings arranged toregister with the opening of the lever, a pivot element connecting thediscs together in spaced relation and insertable in said open slot ofthe lever to detachably and pivotally mount said discs in said lever anda bolt insertable through any openings of the discs and through saidopenings of the lever to secure 10 said discs on the lever in adjustedposition.
